Embodiment
[0020] The amount of domestic sewage in a community is 300 tons / day. The water quality indicators of the sewage before entering the water treatment system are: COD=280mg / L, BOD=150mg / L, ammonia nitrogen=35mg / L, SS=180mg / L. Sewage is treated sequentially through an aeration regulating tank equipped with suspended fillers, a pressure bioreactor and a pressure filter. The effluent water quality indicators of the device are: COD≤30mg / L, BOD≤5mg / L, ammonia nitrogen≤0.8mg / L, SS≤5mg / L, the effluent water quality meets the national sewage recycling standard, and can be reused for flushing toilets and greening after disinfection.

The invention discloses a low-cost community recycled water treatment system. The low-cost community recycled water treatment system comprises a regulating pond, a pressure biological reactor, a pressure filter and a clean water pond. All devices of the low-cost community recycled water treatment system are made of anticorrosive materials, so that the service life is long; and meanwhile, the tail gas discharged by the pressure biological reactor is introduced into the regulating pond with suspending biological stuffing to perform aeration, so that the secondary utilization of the tail gas is realized, and the recycled water treatment power consumption can be remarkably reduced.
Description
technical field [0001] The invention belongs to the field of residential water treatment, in particular to a low-cost residential water treatment system. Background technique [0002] In recent years, with the accelerated development of urbanization in my country, the consumption of urban domestic water continues to increase, and the phenomenon of water shortage is becoming more and more serious. Many cities have serious water shortage problems, and water conservation has become a top priority. The state encourages the construction of reclaimed water facilities in residential quarters, collects sewage through the residential sewage pipe network to the reclaimed water station for treatment, and reuses the treated water after reaching the reclaimed water utilization standard. [0003] At present, residential quarters in many cities in China are equipped with reclaimed water treatment stations, but many residential reclaimed water stations are left unused after completion, main...
